HOT-METAL CAR.

1 Specification of Letters Patent.

Patented Dec. 25, 1917.

Application filed October 13, 1914. Serial No. 866,532.

To all whom it may concern:

Be it known that I, JOHN D. PUGH, a citizen of the United States, and resident of Harrisburg, Dauphin county, State of Pennsylvania, have invented certain new and useful Improvements in Hot-Metal Cars, of which the following is a specification.

This invention relates to hot metal cars for the transportation of molten metal.

The objects of the invention are to provide a car which will have the characteristics of simplicity of construction, stability, and which will prevent spilling of the metal and will, also, reduce radiation or the rate of cooling to a minimum.

It is a further object of the invention to provide a car which is adapted to serve as a storage reservoir for metal taken from a blast furnace and intended to be used in a steel making furnace, means being provided whereby the metal may be reheated in case there is a relatively long period of time between the taking of the metal from the blast furnace and its introduction into the steel making furnace.

It is a further object to provide a car having a ladle whichcan be made in various capacities without changing the lateral or vertical clearances and by using a maximum number of parts which will be standard for different capacities of ladles.

An embodiment of the invention is illustrated in the accompanying drawing in which:

Figure 1 is a side elevation;

Fig. 2 is an end elevation with a part shown in section; and

Fig. 3 is a plan view.

Referring to the drawings, 10 and 11 indi cate trucks, which may be of an suitable construction and which support a ody' comprising the ladle supports 12 and 13, which are connected by a frame 14 having a central depressed ortlon 15. Couplers 16 are attached to t e frame 14 in the usual wa for the purpose of connecting the car with a locomotive or other device for moving th same.

A ladle preferably in the form of a solid of revolution having a horizontal axis and. being symmetrical about a medial vertical plane and comprising a substantially cylindrical middle portion 17 and dished or conical end portions 18 and 19, which are connected to the middle portion, is supported on h m e s 12 and 13 by means of horizontally spaced trunnions 20 forming parts of the members 21 which are secured to the apexes of the conical portions 18 and 19.

The axes of the middle portion 17 of the above the axis of the ladle, and in vertical alinement therewith, these trunnions being adapted to receive lifting chains whereby the ladle maybe-lifted from the car body. On account of the axes of the trunnions 23 being above the axis of the ladle, it will be evident that the center of gravity will be below the axes of these trunnions and therefore the ladle will be in a perfectly stable condition when lifted from the car body.

The ladle is lined with suitable refractory material 24:, as is usual, and spouts 25 are arranged on opposite sides of the cylindrical portion 17 above the axis thereof and substantially within the lateral limits of the cylindrical portion as shown in Fig. 2. The openings 26 through the spouts 25 may be closed 1) means of suitable covers 27, preferably lined with refractory material 28 and having lifting handles 29. The covers 27 are also preferably provided with openings 30 through which a gas burner or other heating device may be inserted for the purpose of maintaining the metal, in the ladle, in a fluid condition.

In order to pour the metal from the ladle, without lifting the ladle from the car body, the trunnions 20 are so arranged that the ladle may be tilted to either side of the car about-the axis of either pair of the alined trunnions at the opposite ends of the ladle. By having the trunnions 20 substantially on the plane of the axis of the ladle, the latter will be supported in a stable manner and also may be readily tilted. In order to facilitate tilting of the ladle, there are provided on the cylindrical portion 17 preferably below the axis thereof and substantially within the lateral limits of the cylindrical portion, lugs 31 to which a chain may be attachedfor lifting either side of the ladle. When the ladle has been lifted from the car body and is supported on the trunnions 23,

. ing the metal therefrom by attaching a lifting chain to either of the lugs 31.

By providing a ladle having a substantially cylindrical middle portion and substantially conical end Portions, it will be evident that ladles of different capacities may be constructed by using middle portions of different lengths. The conical end portions and the supporting members 21 may be the same for ladles of difierent capacities, and furthermore by having the middle portion substantially of the form shown it is not necessary to increase the diameter of this middle portion in order to increase the capacity of the ladle. The lateral and vertical clearances of the car are therefore not changed in making ladles of difierent sizes, and this is of very great importance because the lateral and vertical clearances are usually limited by the sizes of doors, tunnel openings, etc. The substantially cylindrical middle portion also permits the location of the spouts 25 so that they are substantially within the lateral bounds of the middle portion and at the same time are at such an elevationthat practically the full capacity of the ladle may be used without spilling the metal. Thus a ladle is obtained which has a maximum capacity for the'track clearances permitted. It is obviousthat, if.the spouts were located so that they projected outside of the cylinder as seen in plan view, the capacity of the ladle would be correspondingly decreased. The substantially cylindrical and conical portions also provide a ladle of closed construction, the advantages of which are that spilling of the metal is prevented and the radiation of the heat of the metal is reduced to a minimum.

The length of the car body will,'of course, be made to correspond with the length of the ladle so that vfor different capacity ladles it is onl necessary to provide car bodies of corresponding lengths, the other parts bein standard and may be used with ladles of di ferent capacities.

It will be evident that the construction is not limited to one in which the middle portion of the ladle is truly cylindrical or truly circular in cross section and the ends are straight-sided cones, and I therefore use the terms cylindrical and conical in their broad sense and intend the claims to cover suchmodifications of the construction illustrated as come within the spirit and scopeof the invention.

7 Having thus described my invention, what I clalm and desire to secure by Letters-Patcut is:
